Schneider Optics introduced an interesting lens - the new S2000 Century/Canon 17mm T4 Tilt-Focus Lens, which is compatible with the PL Mount. According to the producer it is ideal for use on cameras with up to a S35 sensor, but what's more interesting is that this converted lens offers 360 degrees of rotation and 8 degrees of tilt in any direction for remarkable control of the subject focus plane.
The lens' tilt and rotation adjustments can be made before or during a shot for a wide variety of effects. The desired degree of rotation is fixed via a lever while a locking knob secures the selected tilt angle. The S2000 Century/Canon 17mm lens features a linear iris and integral .8 module metric iris and focus gears.
Other existing lenses in the Tilt-Shift family include: 24mm T4, 45mm T2.8, and 90mm T2.8, US List Price for the Century/Canon 17mm T4 is $7500. For more info visit the official website (here).
